Detailed Product Description

Centric 121.79014 is a vented disc brake rotor engineered for applications that use a 6-lug hub pattern and a behind-the-hub mounting design. With a 390.700 mm outside diameter and 39.000 mm nominal thickness, it is sized for larger braking systems that require a substantial rotor footprint. The smooth face and straight vane layout support even pad contact and heat management in normal service.

This rotor cross-references Monroe Shocks & Struts 172286 and 182286 for the same application. It is a practical choice for buyers comparing Centric 121.79014 against other replacement rotors for Chevrolet Silverado and GMC Sierra brake service.

What This Rotor Helps Address

• Brake pulsation caused by worn or uneven rotor surfaces
• Reduced braking consistency from rotor wear beyond discard thickness
• Noise or vibration associated with rotor surface irregularity
• Service replacement needs for vented 6-lug brake systems
• Brake maintenance on select Chevrolet Silverado and GMC Sierra applications

Installation Notes and Tips

Verify rotor dimensions, hub pattern, and mounting style before installation. Measure the existing rotor and confirm the 6-bolt circle diameter, center hole diameter, and overall height match the vehicle’s brake setup. Replace brake pads and inspect calipers, hub surfaces, and wheel bearings during service to help ensure even rotor contact and proper braking performance.

Because this rotor does not include bearings or an ABS tone ring, reuse or replace those components separately as required by the vehicle. Always follow the vehicle manufacturer’s service procedure for torque, bedding, and final inspection.
